OFFICIAL NASA LIVE STREAM FROM THE ISS

The High Definition Earth Viewing (HDEV) experiment aboard the ISS was activated April 30, 2014. It is mounted on the External Payload Facility of the European Space Agency’s Columbus module. This experiment includes several commercial HD video cameras aimed at the earth which are enclosed in a pressurized and temperature controlled housing. Video from these cameras is transmitted back to earth and also streamed live on this channel. While the experiment is operational, views will typically sequence though the different cameras. Between camera switches, a gray and then black color slate will briefly appear. Since the ISS is in darkness during part of each orbit, the images will be dark at those times. During periods of loss of signal with the ground or when HDEV is not operating, a gray color slate or previously recorded video may be seen.

Analysis of this experiment will be conducted to assess the effects of the space environment on the equipment and video quality which may help decisions about cameras for future missions. High school students helped with the design of some of the HDEV components through the High Schools United with NASA to Create Hardware (HUNCH) program. Student teams will also help operate the experiment. To learn more about the HDEV experiment, visit here: nasa.gov

Would A Catastrophic Air Leak Knock The Space Station Out Of Orbit?

Is it possible to lower the perigee of the space station by decompressing the station through the forward air lock? No, but let's take the opportunity to talk about other cold-gas propulsion systems.

NASA astronauts Nick Hague and Christina Koch, and cosmonaut Alexey Ovchinin of Roscosmos, are set to launch aboard the Soyuz MS-12 spacecraft at 2:14 p.m. EST from the Baikonur Cosmodrome in Kazakhstan.
Liftoff window begins at 2:14 p.m. EST (19:14 GMT).
The new crew members will dock to the Rassvet module at 9:07 p.m. Expedition 59 will begin officially at the time of docking.
The trio’s arrival will return the orbiting laboratory’s population to six, including three NASA astronauts. This launch will also mark the fourth Expedition crew with two female astronauts.
During their mission, the station crew will take part in about 250 research investigations and technology demonstrations not possible on Earth to advance scientific knowledge of Earth, space, physical, and biological sciences, NASA said.
McClain, Saint-Jacques, Hague and Koch also are all scheduled for the first spacewalks of their careers to continue upgrades to the orbital laboratory.
McClain and Hague are scheduled to begin work to upgrade the power system March 22, and McClain and Koch will complete the upgrades to two station power channels during a March 29 spacewalk. This will be the first-ever spacewalk with all-female spacewalkers.

Expedition 59

At the Gagarin Cosmonaut Training Center in Star City, Russia, Expedition 59 crew members Christina Koch of NASA, Alexey Ovchinin of Roscosmos and Nick Hague of NASA report to Russian space officials Feb. 19 during the first of two days of final pre-launch qualification exams. They will launch March 14, U.S. time, from the Baikonur Cosmodrome in Kazakhstan on the Soyuz TMA-52a spacecraft for a six-and-a-half month mission on the International Space Station.

How SpaceX and Boeing will get Astronauts to the ISS

I have all the graphics from this video up on my website if you want to digest them more! - https://everydayastronaut.com/?p=9398&preview=true
We’re at a really exciting time where the number of crewed vehicles going to the international space station will go from just one to three!. The Soyuz’s 8 year monopoly for getting humans to the ISS is coming to an end.
So today we’re going to take a deep dive on the two new spaceships that will be responsible for taking humans to and from the International Space Station from the United States. We’ll compare the Boeing Starliner riding an Atlas V rocket to SpaceX’s Crew Dragon on their Falcon 9 Rocket.
And to see how we’ve progressed in the world of human spaceflight, we’ll also compare all these systems along side Russia’s Soyuz capsule and the United State’s retired Space Shuttle in a side by side comparison.
We’ll look at the designs, the rockets they’ll ride, dimensions, cost, safety considerations, and any other unique features that each vehicle offers.
Considering I’ve been up close and personal with SpaceX’s Crew Dragon Capsule, and Boeing’s Starliner, I’ve got some good insight on some of these vehicles.

International Space Station

A new buzz comes to the International Space Station (ISS): Astrobee. Three free-flying, cube-shaped robots. The robots are designed to help scientists and engineers develop and test technologies for use in microgravity to assist astronauts with routine chores, and give ground controllers additional eyes and ears on the space station. The autonomous robots, powered by fans and vision-based navigation, perform crew monitoring, sampling, logistics management, and accommodate up to three investigations.
The MARROW study (Bone Marrow Adipose Reaction: Red Or White?) (Marrow) investigation looks at the effect of microgravity on the bone marrow. It is believed that microgravity, like long-duration bed rest on Earth, has a negative effect on the bone marrow and the blood cells that are produced in the bone marrow. The extent of this effect, and its recovery, are of interest to space research and healthcare providers on Earth.

Antares/Cygnus: ISS Cargo Resupply

Northrop Grumman’s Cygnus spacecraft was released from the Canadarm2 at 8:16 a.m. PST and has departed the International Space Station. After an extended mission to deploy several CubeSats in multiple orbits, Cygnus is scheduled to be deorbited on Feb. 25 to enter the Earth’s atmosphere and burn up harmlessly over the Pacific Ocean. Expedition 58 Flight Engineers Anne McClain of NASA and David Saint-Jacques of the Canadian Space Agency used the station’s robotic arm to release the craft, dubbed the 'SS John Young', after ground controllers unbolted the cargo vehicle from the Earth-facing port of the Unity module earlier this morning.

Research in space for health: growing blood vessels

By cultivating human endothelial cells in space, researchers are gaining knowledge about the way our blood vessels function. This could help prevent and treat diseases such as atherosclerosis, hypertension, diabetes and thrombosis here on Earth, while keeping astronauts healthy in space.
In this video, biochemist and molecular biologist Dr Markus Wehland discusses the Spheroids experiment, which ran on the International Space Station during ESA astronaut Tim Peake’s Principia mission in 2016.
Cells cultivated in microgravity during this experiment assembled into globular and tubular structures. These structures were similar to the inner lining of blood vessels inside our bodies, but had never been achieved before by scientists cultivating cells on Earth.
Knowledge about cell growth and structure gained through this study could aid the development of tissue engineering techniques to replace damaged blood vessels in patients. It could also improve the efficiency and safety of drugs that help regulate vessel development.
It is good news for those affected by cardiovascular disease and a great example of the way in which research in microgravity is enhancing life on Earth.

NICER Charts the Area Around a New Black Hole

Scientists have mapped the environment surrounding a black hole that is 10 times the mass of the Sun using NASA's Neutron star Interior Composition Explorer (NICER) payload aboard the International Space Station. NICER detected X-ray light from a recently discovered black hole, called MAXI J1820+070 (J1820 for short), as it consumed material from a companion star. Waves of X-rays formed "light echoes" that reflected off the swirling gas near the black hole and revealed changes in the environment's size and shape.
A black hole can siphon gas from a nearby star and into a ring of material called an accretion disk that glows in X-rays. Above this disk is the corona, a region of subatomic particles that glows in higher-energy X-rays.
Astrophysicists want to better understand how the inner edge of the accretion disk and the corona change in size and shape as a black hole accretes material from its companion star. If they can understand how and why these changes occur in stellar-mass black holes over a period of weeks, they could shed light on how supermassive black holes evolve over millions of years and how they affect the galaxies in which they reside.
One method used to chart those changes is called X-ray reverberation mapping, which uses X-ray reflections in much the same way sonar uses sound waves to map undersea terrain.
From 10,000 light-years away, the scientists estimated that the corona contracted vertically from roughly 100 to 10 miles -- that's like seeing something the size of a blueberry shrink to something the size of a poppy seed at the distance of Pluto.

Horizons science – Cimon

ESA astronaut Alexander Gerst welcomed a new face to the Columbus laboratory, thanks to the successful commissioning of technology demonstration Cimon. Short for Crew Interactive Mobile CompanioN, Cimon is a 3D-printed plastic sphere designed to test human-machine interaction in space.
Developed and built by Airbus in Friedrichshafen and Bremen, Germany, on behalf of German Space Agency DLR, Cimon uses artificial intelligence software by IBM Watson. Its scientific aspects are overseen by researchers at Ludwig Maximilians University Clinic in Munich.
This video shows Alexander’s first interactions with Cimon on board the International Space Station. After introducing himself, where he comes from and what he can do, Cimon tests his free-flying abilities, helps Alexander with a procedure and even plays Alexander’s favourite song ‘Man Machine’ by Kraftwerk. In fact, Cimon likes the music so much, he does not want to stop.
Happy with his initial outing, both Cimon’s developers and Alexander hope to see Cimon back in action again soon. While no further sessions are planned during the Horizons mission at this stage, it could mark the beginning of exciting collaboration between astronauts, robotic assistants and possible future artificial intelligence in space.

Expedition 57

Soyuz TMA-50a crew have started the final phase of their trainings for the flight to the International Space Station (ISS). The main crew of ISS-57 Expedition consists of ROSCOSMOS cosmonaut Alexey OVCHININ and NASA astronaut Nick HAGUE. Their backups are ROSCOSMOS cosmonaut Оleg KONONENKO and CSA astronaut David SAINT-JACQUES. Cosmonauts and astronauts tried on their flight spacesuits, and performed their leak test. After taking their places in the vehicle cosmonauts and astronauts tested the radio communication system, laser ranging system, got familiar with the onboard data files, studied the flight program and a list of cargo to be delivered to the ISS and their accommodation locations in the vehicle. During the final training sessions at the launch site training of the space vehicle manual proximity operations to the ISS, audit of science hardware sets, testing of upcoming ballistic operations and other preparatory procedures are also planned. This very day, a Technical Management meeting was held, where a decision was taken to fuel Soyuz TMA-50a with propellant components and compressed gases. The launch of Soyuz-FG launch vehicle with Soyuz TMA-50a with the crew of the next Expedition to the International Space Station (ISS) is scheduled for October 11, 2018 from the Baikonur launch site.

On the forecast track, the center of Florence will approach the coasts of North and South Carolina later today, then move near or over the coast of southern North Carolina and eastern South Carolina in the hurricane warning area tonight and Friday. A slow motion over eastern South Carolina is forecast Friday night through Saturday night. The region is facing potential catastrophic flooding from Florence with some rainfall totals predicted to reach 40 inches.

David Saint-Jacques' training for his space mission

2018-09-05 - David Saint-Jacques has done years of training to be ready for a space mission. Since his assignment to the crew of Expedition 58/59, he has taken customized training on the International Space Station and its various modules, the Soyuz spacecraft, Canadian and international science, and a variety of mission-specific tasks. His training has taken him to Canada, Europe, Japan, Russia and the United States. David Saint-Jacques will fly to the International Space Station in December 2018.

Astronauts repair air leak on the International Space Station

Space agency chief Dmitry Rogozin revealed that the hole in a Russian space craft docked at the orbiting station was caused by a drill held with a 'wavering hand'. A commission will seek to identify the culprit by name, Rogozin said, calling this a 'matter of honour' for Russia's Energia space manufacturing company that made the Soyuz space craft. The 'micro fracture' believed to be around 2mm wide in the $150 billion (£115 billion) space station was discovered after astronauts noticed a drop in pressure on 29 August. Sources suggest the question of how to fix the hole – potentially caused by 'deliberate interference' – may have strained relations between Moscow and Houston.

NASA Live: Earth Views from the Space Station

Behold, the Earth! See live views of Earth from the International Space Station coming to you by NASA's High Definition Earth Viewing (HDEV) experiment.
While the experiment is operational, views will typically sequence through the different cameras. If you are seeing a black image, the Space Station is on the night side of the Earth. If you are seeing an image with text displayed, the communications are switching between satellites and camera feeds are temporarily unavailable. Between camera switches, a black & gray slate will also briefly appear.
The experiment was activated on April 30, 2014 and is mounted on the External Payload Facility of the European Space Agency’s Columbus module. This experiment includes several commercial HD video cameras aimed at the Earth which are enclosed in a pressurized and temperature controlled housing. To learn more about the HDEV experiment, visit: https://eol.jsc.nasa.gov/ESRS/HDEV/
Please note: The HDEV cycling of the cameras will sometimes be halted, causing the video to only show select camera feeds. This is handled by the HDEV team, and is only scheduled on a temporary basis. Nominal video will resume once the team has finished their scheduled event.

Releasing the Dragon

This timelapse video shows still pictures taken from the International Space Station of the departing #Dragon supply spacecraft. Played in quick succession the video displays faster than real life but in 4K resolution.
The Dragon spacecraft was released from the Station’s robotic arm at 18:38 GMT on 3 August 2018. Thrusters fired to increase its distance from the Space Station and the spacecraft started its deorbit and return to Earth, splashing down in the Pacific Ocean less than seven hours after release.
The International Space Station flies at 28 800 km/h above our planet doing a complete orbit in around 90 minutes – during release operations the sun set and rose above the horizon many times.
As Dragon faded into the distance it flew over a stormy part of Earth – lightning flashes can be seen many kilometres below.
Dragon is the only spacecraft that can return to Earth with scientific cargo aside from the Soyuz spacecraft that ferries astronauts to space and back – this flight carried over 1700 kg of cargo.

Bye bye Cygnus

ESA astronaut Alexander Gerst and NASA astronaut Serena Auñón-Chancellor commanded the International Space Station’s 16-m robotic arm to release a #Cygnus supply spacecraft to burn up harmlessly over Earth.
The duo set up the robotic workstation in the European-built Cupola module to follow operations from the observatory. You can see Alexander opening the protective shutters from a window at the start of the video.
The spacecraft was released at 14:17 GMT on 15 July 2018 as the International Space Station flew over Colombia.
Cygnus spent two weeks orbiting Earth on its own allowing engineers to conduct tests as well as releasing a series of miniature satellites before ending its mission.

The power of Dark Energy may be increasing as the universe ages. Subtle clues are emerging that the accepted model for the nature of dark energy and dark matter may not be all that. We saw the first such clue recently in our recent episode on the Crisis in Cosmology. Today we’re doing a Space Time Journal Club to reveal another clue. We’re looking at a new paper in Nature Astronomy, “Cosmological constraints from the Hubble diagram of quasars at high redshifts” by Risaliti and Lusso. It hints that the cosmological constant may not be so constant after all. In fact it may be increasing. If this is true, then our prediction for the future of our universe looks VERY different, and may involve the entire universe tearing itself to shreds at the subatomic level in the Big Rip.
On this edition of Space Time Journal Club we look at:
Risaliti & Lusso (2019) "Cosmological Constraints from the Hubble Diagram of Quasars at High Redshifts"

NASA ScienceCasts: A Super Start to 2019

2019 is an excellent year to look to the sky and enjoy the spectacular view of Earth’s nearest neighbor, the Moon.

Do black holes contain dark matter?

Black holes grow by accreting matter under gravity; so surely they should be able to accrete dark matter? So then is there loads of dark matter trapped inside black holes?
Turns out it's a bit more complicated than that because of what we know of how dark matter behaves - which isn't a lot! - but it's enough.
This was a really fun speculative question to think about, especially because it ties in with my PhD thesis too. Let me know if you want me to do a video describing my thesis down in the comments.
Both my lapel microphones ran out of battery this week. Thankfully one of them didn't need a battery to use with a smartphone, so the sound was recorded that way. It's not brilliant I know, but it'll do. My research schedule this week stopped me from delaying filming until I could get a battery. The sound suffered so science wouldn't.

Space Weather News | A Filament Sandwiched by Sunspots 03.20.2019

UPDATE: Part of the filament I talk about did erupt after I posted this video! We could have a part-Earth directed solar storm coming by the end of this week! Check my twitter feed for the latest on arrival time!
Original Video Description:
This week we are coming down from a solar storm from some fast solar wind, but that doesn't mean the fun is over! We have two fast-growing sunspots on the Earth-facing Sun and they are sandwiching a filament that is growing more unstable by the day. If this filament erupts within the next day or so, we could have an Earth-directed solar storm! We are keeping a close watch on this to be sure. Also, one of the new sunspots may be showing signs of an influence of solar cycle 25. Just like the previous rogue sunspot we saw a few weeks ago, this new region has a dominant magnetic signature that runs north-south instead of east-west. Its too early to tell what the final polarity of this region will be, but if it continues this way, it will be yet another signal that solar cycle 25 is closer than we think! Learn the details of this filament sandwich, get the scoop on the two new sunspots that may cause its launch, and see what else our Sun has in store for us this week!
